This invention relates to an improved mechanical movement, particularly for converting pendulum-like or swinging motion to rotary motion or vice versa, and the present application describes an improvement over my prior Patent No. 1,694,961 granted on December 11, 1928.

One of the important objects of this invention is the provision of means for converting pendulum-like or swinging motion into rotary motion or conversely, a rotary motion to a swinging motion, and one of the main objects of this invention is the construction of a device which may be particularly applicable for utilizing certain types of reciprocating power as, for example, the motion of waves.

Another important object of the invention is to provide a special type of control means in connection with a swingingly operated source of power which, in turn, operates to impart motion to a rotary element. This control means acts as a compensator for otherwise irregular movements as will quite often occur in the case of wave motion or the like.

Other and further important objects of the invention will be apparent from the disclosures in the accompanying drawing and following specification.

The invention, in a preferred form, is shown in the drawing and hereinafter more fully described.

In the drawing:

Figure I is a side elevation of the improved machine of my invention, illustrating one embodiment thereof.

Figure II is an end View of the apparatus shown in Figure I, parts being broken away.

Figure III is a view somewhat similar to Figure I, showing a modified form of the invention.

Figure IV is an end view of the device illustrated in Figure III.

Figure V is a View of the bottom of the apparatus shown in Figure III, illustrating a further modification.

As shown in the drawing:

The reference numeral I indicates generally 5 the upright sup-ports or framework of the improved machine of this invention, the same being preferably supported on a base or platform 2 which obviously may be modified to suit requirements, localities or conditions.

Along the top of the supports or frame elements I, a pendulum-like structure I is supported which has a vane or the like 8 extending therefrom so as to present a fairly broad surface for wave contact. The pendulum is swung from a pivotal point 60, and a roller la is mounted in a slot 1b in the pendulum I, the same being mounted on the end of an arm or crank II. The slot lb extends practicallythroughout the length of the pendulum.

The swinging operation or tension of the pen- 5 dulum can be adjusted by means of springs 6 which are attached to extensions 5b of the frame I, and it will be noted that the pendulum I has an upwardly ext-ending projection 9 which has an opening It therethrough, there being a curved l0 rod 5 fitted through the opening, the curved rod 5 having its ends adjustably supported in the frame extensions 5b. Bumper springs 50. are mounted on the rod 5 so as to also further control the action of the pendulum. A weight I6 is 15 fixed to the lower end of the pendulum to assist in producing a smoother motion.

The crank I1 is fixedly mounted on the end of a shaft I8 fitted in suitable bearings in the framework I, and upon this shaft is fixed a wheel 20 3 having a counterweight 3a fixed at a desired point on its periphery.

Obviously, swinging of the pendulum I and vane 8 through an arc of sufiicient length will impart a rotary motion to: the shaft I8 and the 25 wheel 3, the counterweight 3a and the springs 5a and 6 assisting to compensate for the irregularities in both movement and power of thrust. Conversely, a rotation of the fly wheel 3 will impart a swinging movement to the pendulum by 30 means of the action of the end of the crank I! in the slot in the pendulum. When the pendulum is used to impart rotary motion to the fly wheel, its swing must be sufiicient to allow or produce a complete revolution of the end Ia of the crank 35 II.

In Figures III and IV is described a modified form of the invention wherein a base 20 supports side frame elements 22 in which elements is mounted a rotary shaft 24 supporting a fly-wheel 40 or the like 26. This fly-wheel is provided with two counterweights 28.

Another shaft 30 extends across the topof the framework and supports a pair of pendulums or vane structures 32, one at each side of the device. 45

The pendulum structures themselves have slots 34 therein in which rollers 35 operate, the rollers, in turn, being mounted on extensions fitted to the ends of cranks 36 fastened on the shaft 24.

As best shown in Figures III and IV, compensat- 5 ing springs are also provided in this case for any irregular motions, there being two sets of these springs, one set comprising a pair as shown at 38, the upper ends of each of the springs 38 being attached to a common fastening point 40 near the 55 upper end of the pendulum and having their lower ends affixed to pins on the corresponding ends of a cross-bar or the like 42 fastened to the frame 22.

In addition, there is another pair of compensating springs 44, the ends of which are mounted on an extension 46 near the top of the frame and which converge downwardly toward the pendulum and are aflixed thereto at opposed brackets 48-thereon.

As best shown in Figure V, another set of springs 50 may be attached to the lower end of the pendulum, the outer ends of the springs being mounted on corresponding adjacent parts of the framework 22.

It will be evident that herein is provided a compensated mechanism for converting swinging movement to rotary motion and. which will auto-- matically take advantage of any irregularities of power or swing which may occur in the source of reciprocating motion.

I am aware that many changes may be made and numerous details of construction varied throughout a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art.

I claim as my invention:

1. A'device for converting reciprocating to rotary motion, comprisinga framework, a shaft and fly-wheel mounted in the framework, counterweights on the fly-wheel, a pair of reciprocating elements swingingly mounted on the framework, and a crank-shaft connection between said elements and the rotary shaft, said crank-shaft connection including a roller mounted in a slot in the swingable elements, and vanes on said swingable elements projecting outwardly therefrom, together with means for controlling and compensating irregularities in the pendulum-like motion of said swingable elements.

2. A device for converting reciprocating to ro tary motion, comprising a framework, a shaft and fly-wheel mounted in the framework, counterweights on the fly-wheel, a pair of reciprocating elements swingably mounted on the framework, and a crank-shaft connection between said elements and the rotary shaft, said crank-shaft connection including a roller mounted in a slot in the swingable elements, and vanes on said swingable elements projecting outwardly therefrom, together with means for controlling and compensating irregularities in the pendulum-like motion of said swingable elements, said means comprising helical springs, one end of each spring being connected to the pendulum and the other ends being attached to opposed points on the supporting frame.
